In this simulator you can design your own evolved version of a bunny. To change each body part you click on it, and it will cycle through a few variations. 1. Head size - Determines how smart the bunny is. 2. Ear size - Determines how well the bunny hears. 3. Body color - Determines how well the bunny can camoflage to its environment. 4. Tail size - Determines the bunny's evasion ability. 5. Environment - select any environment. Once you design your bunny, click start and the Bunny will start trying to survive in the wild. If it has good evolutionary traits it will survive and breed, if not then it will die out.
